when building packages (e.g. for openSUSE Linux) (random) filesystem order of input files influences ordering of functions in the output .so files. Thus without the patch, builds (in disposable VMs) would usually differ. Without this patch, all callers have to be patched individually ofalk/libdnet#42 sass/libsass-python#212 tahoe-lafs/pycryptopp#41 yt-project/yt#2206 pyproj4/pyproj#142 pytries/datrie#49 Roche/pyreadstat#37 but that is an infinite effort. See https://reproducible-builds.org/ for why this matters.

This has been pulled in https://github.com/ofalk/libdnet - I'll try to provide the base there for further development, since here nothing is happening any longer. |

so that dnet.so builds in a reproducible way
in spite of indeterministic filesystem readdir order
and http://bugs.python.org/issue30461
See https://reproducible-builds.org/ for why this is good.
This allows the libdnet package in openSUSE Tumbleweed
to produce identical rpms on different builds.
